Given 41, 253 square degrees of sky, the odds that such a noticeable star would occupy the right spot are nearly 1, 000-to-1.
33.
It is a mid-sized constellation, ranking 39th overall size, with an area of 441 square degrees ( 1.1 % of the celestial sphere ).
34.
One of the largest constellations in the night sky, its 1279.66 square degrees of surface area being equivalent to 3.10 % of the total sky.
35.
The survey studies galaxies more than a billion light-years distant, across an area greater than a thousand square degrees ( about one fortieth of the entire sky ).
36.
A 1960 ?2560 pixel CCD which covered the telescope's two-square degree field of view was then installed, and both detectors were used in later tests.
37.
These 4096?096 pixel cameras provide a field of view of 1 degree square on with the 1.5-m telescope and nearly 9 square degrees with the Catalina Schmidt.
38.
"Kepler " field of view covers 115 square degrees, around 0.25 percent of the sky, or " about two scoops of the Big Dipper ".
39.
To complete this survey it will take 1929 hours, covering 10 9 stars within an area of 520 square degrees, including 33 known globular clusters and around 350 open clusters.
40.
As a southern hemisphere survey covering 20, 000 square degrees of the sky, RAVE's primary aim is to derive the radial velocity of stars from the observed spectra.
